FOUNTAIN TYPE PLASTERER'S BRUSH Filed May 24, 1956 INVENTOR ATTORNEYS United States Patent FOUNTAIN TYPE PLASTERERS BRUSH William T. Martin, Jr., Hammond, Ind.

Application May 24, 1956, Serial No. 587,136

1 Claim. (Cl. 15-133) This invention relates to brush construction designed primarily for plasterers use in spreading or applying water to a plastered wall surface when troweling or finishing such wall surface.

An important object of the invention is to provide a brush or spreader for plasterers use in finishing walls, the head of the brush being of the fountain type so that when the spreader blade is dipped into a bucket containing water, a quantity of water will be taken into the head of the brush through a small opening formed in the handle adjacent to the head of the brush for delivery to the spreader'blade, thereby eliminating the necessity of dipping the brush into the water bucket with each application of the brush to the surface under treatment.

Another object of the invention is to provide a plasterers brush embodying a hollow head providing a reservoir, said head having spaced parallel flanges extending from one edge of the head, and between which flanges the brush blade is supported.

Still another object of the invention is to provide a plasterers brush having a handle and a hollow head from which water passes onto the rubber spreader blade secured within the head, while the brush is in use in applying water to the surface.

Other and further objects and advantages of the invention will be hereinafter described and the novel features thereof defined in the appended claims.

Referring to the drawing:

Fig. 1 is a side elevational view of a plasterers water applying brush, constructed in accordance with the invention, a portion of the head having been broken away illustrating the construction of the interior of the head of the brush.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Referring to the drawing in detail, the brush comprises a handle Sand a head 6 cast integral therewith.

As better shown by Fig. l of the drawing, the upper surface of the head 6, at opposite sidesof the handle 5, slopes downwardly providing the top to the reservoir or container for water held by the brush. 7

It will of course be understood that the handle and head are hollow and the handle communicates with th interior of the head at a point intermediate the ends of the head.

A vent opening indicated at 7 is formed in the end of the handle 5, as shown by the drawing, the vent opening being normally closed by the plug 8 which may be removed readily when it is desired to submerge the head of the brush in a bucket of water to fill the head and handle of the brush with water to be spread by the brush.

A second opening indicated by the reference character 9 is formed in one wall of the handle 5, at a point. adjacent to the inclined upper walls of the head 6 of the brush. This opening 9 provides an inlet opening so that when the head of the brush is submerged in a bucket of water and the plug 8 is removed, water will enter the brush head and handle, through the opening 9 for distribution to the wiping blade indicated by the 2,864,109 latented Dec. 16, 1958 reference character 10. The wiping blade 10 is in the form of a block of sponge rubber which is of a length slightly greater than the length of the head 6. This wiping blade fits between the side walls of the head 6, as shown by Fig. 2 of the drawing, where the wiping blade is cemented or otherwise secured between the side walls.

The edge of the wiping blade that extends between the side walls of the head 6 of the brush, has its inner edge, or the edge fitted within the head of the brush, inclined downwardly in opposite directions, from the center of the wiping blade, so that a wide compartment 11 or tank is provided between the inner edge of the wiping blade and inner surface of the head proper.

The longitudinal edge of the wiping blade that is exposed after the blade has been secured to the brush head, is split throughout its length providing a pair of surface contacting sections 12 which not only lend flexibility to the wiping blade, but at the same time acts to trap water between the surface contacting sections '12 to be distributed over the surface over which the brush is moved.

From the foregoing it will be seen that due to the construction shown and described, I have provided a brush designed for use by plasterers in applying water to a plastered surface in finishing the surface.

Because of the novel construction of the brush, it is obvious that a quantity of water will be supplied to the spreading blade of the brush without the necessity of dipping the brush into a bucket of water with each application of the brush to a surface being treated.

It might be further stated that when the brush is submerged in a bucket of water, water will enter the opening may be made without departing from the spirit and scope thereof as defined in the appended claim.

What is claimed is:

A water application brush for use in finishing plastered surfaces comprising a hollow head having an upper surface, side walls extending downwardly therefrom, and open ends, a hollow handle communicating with said head at a central point thereof, a filling opening in the end of said handle, a plug for said filling opening, a sponge rubber wiping blade clampingly engageable between said side walls, said blade being so dimensioned as to extend beyond the open ends of said head and below said side walls, the top of said blade interiorly of said head being tapered upwardly, the tapered sur face thereof abutting the head at the top of said open ends to prevent accidental lateral displacement thereof, said blade having a longitudinal slot in the outer face thereof and extending the full length of the blade, said handle, head and blade lying in substantially the same plane.
